Creating own list

I have to create my own list in my application. This is a rule in the application.
I need to add, remove and iterate through this list. How to create my own list without extending or implementing any collection classes ?
I think i hav to go for "native" method in java. And i hav to write code in C to dynamically allocate memmory.
Is there any other easy way to do this ?

I think this will have more memory footprints and also it will affect the performance.You haven't said what kind of list you are implementing.
If you are implementing an arraylist, then you have an array, and then when it is full you allocate a new bigger array and copy elements over, and use that bigger array. You only use one array at a time. This is exactly how it is implemented in every language (Java, C++, etc.) so your comments don't make any sense at all.
If you were implementing a linked list, then you wouldn't use arrays at all, and you would allocate individual nodes.

When I look at the demo on the page it fires the same response as that is part of the error handling because it is a standalone HTML and not on a sharepoint server so I am wondering if something I am missing on the submit.click function or batchcmd.

//the hyperlink from actually navigating away from the page or to an anchor.
event.preventDefault();

// Prevent submission if the crossword isn't completed.

alert( "You have left some answers blank. Please complete all answers before submitting." );
$( this ).removeProp( 'disabled' );

Creating a list with different row sizes...

I'm new to AS 3.0 and CS4 and I've been getting up to speed
on all of it. I've used the List component before with my own
CellRenderer. I now need to create a list with different row
heights. The List component is great and does everything that I
want but it requires all rows to be the same height.
I'm unsure of where to go. Creating my own class seems like a
lot of work. The TileList and Grid components don't allow different
sized (and dynamically changing) row heights either. Is there some
base class (SelectableList? BaseScrollPane?) that I should extend
or do I need to just bite the bullet and write it all from scratch?
I need each row to have it's own height and interaction with
a row could change the height of the row. The main use is a list of
data. If the user clicks in an item, it turns the display into
something they can edit (which will need more height).
Thanks for any thoughts on a direction I should think about.
By the way, I really like that AS 3.0 is much more consistent of a
programming language than previous MX versions that I've used.
We're doing a lot of AS/Flash/AIR work with it and it's turning
into a wonderful environment...

Any ideas about this??

Problem in creating a list.

Hello!
How do I create a list in an applet? What do I need to import? I have a simple applet below that contains a list. Yet when I compile it, en error message comes up. The error is shown below.
import java.awt.*;
import java.applet.*;
public class ListApplet exteds Applet
List list;
public void init()
list = new List( 5, false );
add( list );
resize( 300, 150 );
the code above encounters the error:
ListApplet.java:11: cannot resolve symbol
symbol: constructor List (int,boolean)
location: class List
list = new List( 5, false );
1 error
what do I have to do to make this work? I'm a beginner in java. Please be specific when suggesting solutions. Thanks for your help! I really appreciate it!

There seems to be no problem with your code
From your error message, it seems that your code cannot find the constructor for java.awt.List
Did you write a class on your own by the name List because it will overide the one in jdk
if you did write a code by the name List you may rename the class or add in another constructor to take in (int, boolean) as parameter
nope. I didn't write a class named List. I already have my classpath set to (.) and path to ...c:\jdk1.3\bin.

http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSTL7.html says:
The JSTL SQL tags for accessing databases listed in Table 14-8 are designed for quick prototyping and simple applications. For production applications, database operations are normally encapsulated in JavaBeans components.

Create a list

How do I creat a list of records. I can't use an array because the groupings have different number of records and the records have different data types. For example
a record consists of a group, section, and a task/test. How do I create a list of these for me to process and report on downstream in my application?

Make an array of clusters. (This is going to get complicated, so I am
making a list)
On the FRONT PANEL:
1.Make a cluster
2.Make 3 arrays of strings labeled group array, section array, and
task/test array, then drag these arrays into the cluster listed
above.(I suggest strings because they can pass text and numbers
easily)
3.Make an array, then drag the cluster listed above into this array.
This will now make n copies of your cluster, each one having it's own
trio of arrays inside.
If for intance, a particular case has more than 1 task/test, start
listing the tasks in task/test array. Then when you finally unbundle
the arrays, do whatever you need to do until each array is empty.
Remember that making arrays and clusters eats up large amounts of
memory quickly, so this will probably slow the computer down.

Help with creating a list, adding to it, calling it and putting it in a combobox with c#

I have been making a word RPG game with the windows form in c#, and I have encountered some problems along the way. Right now I have a character creation screen, and a screen that displays all of the stats, and gear equipment. I was thinking about adding
some basic/starting items and put the list into a combobox. I created a separate class and named it HeadItems.cs, and put all of the possible stats, as well as ID and string name. I set a constructor with many parameters, so I can simply input this code, and
have it generate a head item.
HeadItems.Add(new HeadItem("Test Head", 0,2,0,0,1));
Then I was trying to make the combobox, called cboHeadItems, and put its DataSource as HeadItems. Though I am not sure how to get it so it displays the first array, or the string name in the combobox. I am also not sure if I should create the list in the
player entity class or its own class. From there I am not sure how to call the list on other forms/classes or how to make the name appear in the combobox for people to select.

Hiya!
It isn't that simple I'm afraid! You cant make the datasource of a combobox a 'HeadItem' because it doesn't know what that is and it won't know how to handle it.
There are a few different ways to do it. You can pass it an array, a dataset, a datatable to mention just a few.
Probably the simplest way is this:
foreach(HeadItem hi in HeadItems){
comboBox1.Items.Add(hi[0]); //Depends on your setup

What is the condition for fetching "Recently Created Opportunities" list

Hello All,
I need to know ,What is the condition to fetch "Recently Created Opportunities" list from Opportunity Home Page.
As mentioned
Name Recently Created Opportunities
Description Opportunities sorted by Created Date
List Accessibility Public (everyone can use it)
Search In All records I can see
Created: Date External Descending
But I need to how many top(?) or range(?) Opportunities sorted by Created date descending order.
Any information will helpful to me.
Thanks & Regards,
Santosh Nayak

I believe recently created opportunities list shows all the opportunities in descending order.(created date).
You should be able to create your own recently created list by adding additional filters.

Creating distribution lists in SAP CRM 5.0 business workplace

Hi Experts,
We have CRM 5.0 and I have tried to create distribution lists for
mailsending.
After defining a name and a folder (that is then created) for the
list the recipient list insertion is a following task.
I can search for partners of different type by F4 help but no
matter the type of the partner searched - the type that is
automatically entered to the lists recipents table is "shared
distribution list". even though the desired type is among others
in a list other values cannot be selected.
Please help, is this a setting that can be undone or what might
be a problem in the procedure that i use in creating a list?
has anyone else had similar problems?
Thank You so much,

i have received an answer from SAP:
"The reason for the error is a wrong entry in table TBCS_RECIP. To removethis entry, please use the report which is entered in the description
of note 735795 or delete the wrong entry direct on table TBCS_RECIP.
After the run of the report or the deletion on table TBCS_RECIP you willnot find further the selection option 'Business Partner' on the F4 help."
The entry was removed and for Lists business partners cannot be selected at all - as a standard. really sad endeed.

Create a list style with unique space after the last list item?

I should start by saying that I'm a web designer and therefore extremely used to using CSS for type setting to the point that I now become frustrated when going back to the print world
So here's what I'm trying to achieve:
- I want to create a list style for bullet lists
- I want there to be 3pt space after and space before paragraph breaks
- I want there to be 9pt space after the entire list (or last list item)
I can't for the life of me figure out how to do this short of overriding the space after amount on the last item each time I use my style.

Hi supportneeder
Welcome to the forum.
Try this link:
http://www.freeforum101.com/iworktipsntrick/viewtopic.php?t=179&mforum=iworktips ntrick
Pay attention to how +"styles work by example"+. Form up the list levels the way you want them and then select them to make the list style.
Personally I can't help remarking on the obtuse behavior of programmers that they manufactured all the problems on the internet and only now, more than a decade later, patch together "solutions" they struggle to implement due to the legacy of all the awful standards we never needed to have in the first place.
Peter
btw The last list item is always a problem in typesetting. Usually you deal with it by having a particular style for that or the paragraph afte,r all of which can take multiple forms.

How to create a list based on a value in multiple sheets

I am trying to create a list in numbers that references a common value among multiple sheets. I have 4 sheets created for a fantasy football league (1 sheet for QB, 1 for Running Back, 1 for Wide Receiver and 1 for Tight End). I have assigned a value to each player listed on each individual sheet. I would like to create a 5th sheet that lists the players in order from highest to lowest value as they are marked on their position sheet. How would this be done in Numbers?
Thanks for the help!

Here is one possible solution:
I named the four data tables "QB", "RB", "TE", and "WR", and the 5th table, for lack of a better name "Summary".
NOTE: The first row OF EVERY TABLE is a header.
In the summary table:
A2=OFFSET(INDIRECT(A$1&" :: $A$1"), MATCH(LARGE(INDIRECT(A$1&" :: B"), ROW()-1), INDIRECT(A$1&" :: B"))-1, 0, 1, 1)
select A2 and fill to the right, then select A2 thru D2 and fill down as needed

How do I create a list of only weekdays in Numbers?

I would like to create a list of weekdays in one column. Using the highlight & drag method doesn't work, as Numbers repeats the highlighted list, instead of extending it. Here is what I am looking for:
1/3/2011
1/4/2011
1/5/2011
1/6/2011
1/7/2011
1/10/2011
1/11/2011
1/12/2011
1/13/2011
1/14/2011
1/17/2011
12/31/2011
Any ideas on how to accomplish this easily?
Thanks!

All i did was type in the first weeks worth (say Jan 2 through 6). You can type the first and fill down for the other 4. Then in the next cell down (B6) just enter =B1+7
This will add seven days to the first "monday" located in B1. Fill it down and it will continually add seven days to the date 5 rows above it.
NOTE: this does not account for holidays. If you need holidays excluded, we need another method

How Do i create a list that will show in a dropdown box with the list being pulled from another tab and not the cell data format junk?

How Do i create a list that will show in a dropdown box with the list being pulled from another tab and not the cell data format junk?
I currently run OS X 10.10.1
Now i have been trying to work on this for a while now and what i want to do should be simple but its apparently not.
Here is an example of what i want to happen.
I will have 2 tabs: Contact | Sales
Now Contacts will have the list of names and various information about a customer, While Sales will have one drop-down box for each Cell Row that will show the names of the person in tab contacts
for what i am wanting to do i cant use the data format pop-up menu because the list is edited everyday several times a day.
Now how do i do this, Excel can do this so how can numbers do it?

How to create a list from checkboxes using Numbers on iPad?

I am creating a guest list using Numbers foriPad. First sheet is a list of invited people with checkboxes (Yes/No/still to reply) in next column. In the next sheet i want create a list of everyone that has replied yes.
I have tried using the if statement, but I dont want any blank cells.
-IF(A2;TRUE;A1) gives name in A1 if box is checked, but gives 0 or something else if i specify. But i want to automatically start on next row to avoid blank or 0-
Example:
David   V
Lisa.     V
Derek
Brad.   V
Paul.
John
The separate list in another sheet should then be:
David
Lisa
Brad
Any help will be appreciated.

Can you use the the reorganize panel to sort the list?
Idon't have Numbers on the iOS so I am not sure. You are posting in the forum for Numbers on Mac OS X.
you can also add a new column (let's say C)
where
C1=if(A1, A1, "")
this will include the name from column A when the checkbox in B is checked. You can then copy column C and paste values using the menu item (Edit > Paste Values, or equivalent in iOS... not sure what it is)
